Cybersecurity experts have found a huge cache of stolen data containing 26 million logins for popular websites including Amazon, Facebook and Netflix.
Hackers used malware to steal 1.2 terrabytes of data, including payment information, from three billion Windows-based computers between 2018 and 2020.
The massive data breach was discovered by cybersecurity firm Nordlocker, who said that a so-called ‘nameless malware’ had been used to collect data from user devices.
This type of custom malware, which was transmitted via email and illegally downloaded software, can be bought online for as little as $100 (£70), the firm says.
